Use of inhibitors of the sodium-hydrogen exchanger for the production of a pharmaceutical for the treatment of disorders which are caused by protozoa

ABSTRACT

Inhibitors of the sodium-hydrogen exchanger are suitable on their own or in combination with other classes of active compound for the production of a medicament for the treament of diseases which are caused by protozoa; thus of diseases which are caused by animal- and human-pathogenic protozoa, such as by intracellularly active parasites of the classes Apicomplexa and Zoomastigophorea, in particular trypanosomes, plasmodia (malaria pathogens), leishmanias, babesias and theilerias, cryptosporidiidae, sarcocystidae, amoebae, coccidia and trichomonads. NHE inhibitors are particularly preferably suitable for the production of a medicament for the treatment of tropical malaria, of tertian malaria, of quartan malaria, as well as toxoplasmosis, of coccidiosis, of intestinal sarcosporidosis, of cryptosporidosis, of Chargas&#39; disease and of the cutaneous and visceral as well as other forms of leishmaniases; and also for the production of a medicament for the treatment of animals which have been infected by animal-pathogenic protozoa, such as by Theileria parva, the pathogen of East Coast fever of cattle, Babesia begemina, the pathogen of Texas fever in cattle and buffalo, Babesia bovis, the pathogen of European bovine babesiosis, and babesioses in dogs, cats and sheep, sarcocystidae, the pathogens of sarcocystoses in sheep, cattle and pigs, cryptosporidiidae, the pathogens of cryptosporidosis in cattle and birds, coccidia, the pathogens of coccidioses of rabbits, cattle, sheep, goats and pigs, but in particular of chickens and turkeys.

DESCRIPTION

Use of inhibitors of the sodium-hydrogen exchanger for the production of a pharmaceutical for the treatment of disorders which are caused by protozoa.

The invention relates to the use of inhibitors of the cellular sodium-hydrogen exchanger for the production of a pharmaceutical for the treatment of diseases which occur as a result of attack of humans and animals by protozoa.

Inhibitors of the sodium-hydrogen exchanger (NHE) have in recent years been characterized in numerous preclinical studies as substances which in the case of restricted circulation of the heart are suitable in a superior manner to protect endangered heart tissue from death. The protection of the heart tissue in this case includes all forms of heart damage caused by inadequate circulation, starting with cardiac arrhythmias via hypercontraction of the heart muscle and temporary loss of function up to death of the heart tissue and permanent damage associated therewith.

The mechanism of action of the NHE inhibitors is that they decrease the increased influx of sodium ions which arises in inadequately supplied tissues as a result of intracellular acidification and subsequent activation of the NHE. Since sodium and calcium ion transport are coupled to one another in mammalian tissue, the life-threatening calcium overloading of the cells is thus also prevented. This unique mechanism relates relatively specifically, in particular, to heart tissue.

It was therefore surprising, as could now be found, that NHE inhibitors are able to kill protozoa having a pathogenic action on humans and animals or to significantly restrict the survival ability of protozoa. Inhibitors of the sodium-hydrogen exchanger are therefore suitable on their own or in combination with other classes of active compound for the treatment of diseases which are caused by protozoa.

Animal- and human-pathogenic protozoa of this type are preferably intracellularly active parasites of the classes Apicomplexa and Zoomastigophorea, in particular trypanosomes, plasmodia (malaria pathogens), leishmanias, babesias and theilerias, cryptosporidiidae, sarcocystidae, ameeba, coccidia and trichomonads.

Particularly preferably, NHE inhibitors are suitable for the treatment of tropical malaria, which is caused by Plasmodium falciparum, for the treatment of tertian malaria, induced by Plasmodium vivax and Plasmodium ovale, for the treatment of quartan malaria, caused by Plasmodium malariae, and for the treatment of toxoplasmosis, caused by Toxoplasma gondii, of coccidiosis, caused by Isospora belli, of intestinal sarcosporidosis, caused by Sarcocystis suihominis, of cryptosporidosis, caused by Cryptosporidium parvum, of Chargas' disease, which is caused by Trypanosoma cruzi, of the cutaneous and visceral and also other forms of leishmaniases, and also for the treatment of animals which have been infected by animal-pathogenic protozoa, such as by Theileria parva, the pathogen of East Coast fever of cattle, Babesia begemina, the pathogen of Texas fever in cattle and buffalo, Babesia bovis, the pathogen of European bovine babesiosis, and also babesiosis in dogs, cats and sheep, sarcocystidae, the pathogens of sarcocystoses in sheep, cattle and pigs, cryptosporidiidae, the pathogens of cryptosporidosis in cattle and birds, coccidia, the pathogens of coccidioses of rabbits, cattle, sheep, goats and pigs, but in particular of chickens and turkeys.

In the treatment of diseases which are caused by human- and animal-pathogenic protozoa, the NHE inhibitors can be administered both orally and parenterally. In this case, NHE inhibitors are used as monosubstances and in combination with other active compounds. Since with NHE a novel principle of action is concerned, combinations with pharmaceuticals which are already used for the treatment of the respective protozoa-related disorder are also advantageously utilizable, a favorable, additively reinforcing action being observed.

Very particularly preferably, the NHE inhibitors are suitable for the treatment of forms of malaria, in particular for the treatment of malaria tropica. At present, between 300-500 million people suffer from malaria, and every twelve seconds a person dies from the consequences of this infectious disease. The number of cases of malaria will in-all probability increase still further in the next few years, since effective methods for the control of malaria are lacking at present. Medicaments which have been employed up to now against malaria have largely lost their efficacy. The malaria pathogens, protozoa of the genus Plasmodium, have become resistant. In order to avert the impending catastrophe, according to the World Health Organization novel pharmaceuticals are urgently needed for the prophylactic and curative treatment of malaria. In this connection, the development of novel medicaments against malaria has proven to be very difficult.

It was therefore surprising that NHE inhibitors have proven effective not only against chloroquine-sensitive but also against chloroquine-resistant Plasmodium falciparum strains. In addition to the treatment of the later erythrocytic stage of the malaria pathogen, which was customary up to now, with NHE inhibitors the treatment of the early form of malaria also appears to be very particularly advantageous due to destruction of the pathogens even in the liver.

In what follows, the activity of NHE inhibitors against protozoa is described:

Culture of Plasmodium falciparum

Erythrocytic stages of the human malaria parasite Plasmodium falciparum were cultured in RPMI 1640 medium, with L-glutamine, 25 mM HEPES, 4 μg/ml of gentamycin, 10% human serum and 5% human erythrocytes, according to Trager and Jensen (1976). The cultures were kept in Petri dishes (10 ml per dish with 10 cm diameter) and incubated at 37° C. in an atmosphere of 92% nitrogen, 3% carbon dioxide and 5% oxygen. The medium of the cultures was changed daily. At a parasitemia of at most 10%, the cultures were diluted. In order to synchronize the cultures, the infected erythrocytes were washed in 5% strength sorbitol solution according to Lambros and Vanderberg (1979). Only the ring stages survive this treatment.

Determination of the IC₅₀ values of the various NHE inhibitors

The half-maximal inhibitory concentration of various NHE inhibitors for the growth of Plasmodium flaciparum was measured in 96-well microtiter plates by incorporation of radioactive hypoxanthine according to Desjardins et al. (1979). In this case, the parasites were cultured for a complete erythrocyte cycle lasting 48 hours in the presence of the corresponding NHE inhibitors.

The NHE inhibitors were dissolved in DMSO and prediluted in physiological saline solution (150 mM NaCl). The dilution series of the NHE inhibitors in 10-fold concentrated 20 μl aliquots was initially introduced onto the microtiter plates, 180 μl of parasite suspension in culture medium were then added to each one. The parasites were in the ring stage with a parasitemia of 1%. The microtiter plates were then incubated for 24 hours. In order to change the culture medium, 150 μl each of supernatant from each well were removed and replaced by 135 μl of new medium, additionally supplemented with 2 μCi/ml of [3H]-hypoxanthine. The concentration of the NHE inhibitors was again adjusted by adding 10-fold concentrated stock solutions in 15 μl aliquots. After incubation for a further 24 hours, the cultures were harvested by filtration on glass fiber filters and the incorporated radioactivity was measured. The percentage inhibition of the tritium incorporation was related to a control without NHE inhibitor.

The IC₅₀ values of the various NHE inhibitors were measured on a chloroquine-sensitive (HB3) and a chloroquine-resistant (Dd2) strain.
